Welcome to issue number one hundred and sixty-four of Hashtag Jakarta EE!

I am right now on my way home after DeveloperWeek 2023. You can read about it in my blog post about the event. But there is no rest for the brave. Next week, I will be at ConFoo 2023 in Montreal where I have two talks scheduled.

Planning for Jakarta EE 11 continues in the Jakarta EE Platform Project. Currently, feedback is being requested from the various individual component specifications. Join the weekly Jakarta EE Platform project call if you want to be a part of the planning for Jakarta EE 11.

At the beginning of March, there will be a Jakarta EE hackathon organized by Payara where you can win up to £3000. I am going to be one of the judges, and I look very much forward to seeing what the participants are able to come up with.

Also, remember to sign up for Devnexus 2023, where there will be a dedicated track with Jakarta EE content.

DeveloperWeek 2023

I have visited San Francisco multiple times before, but this is the first time I have been to Oakland which is just across San Francisco Bay. The city, a short ferry ride from its more famous neighbor, has its charm and is definitely worth a visit if you’re in the area. It is also my first time speaking at DeveloperWeek at the Oakland Convention Center.

My talk titled Jakarta EE for Spring Developers went well. All the demos worked as expected, which is a good thing since the better part of the talk consisted of live demos. The talk was scheduled as the first talk on the first day of the conference, the so-called workshop day, so the attendance was a little lower than expected. But the attendees seemed happy and I got comments that it was very relevant and helpful for them as they were just about to start their migration from Spring Boot 2 to Spring Boot 3.

Another highlight of my DeveloperWeek 2023 experience was receiving the 2023 DEVIES Award for Jakarta EE 10 in the Programming Languages & Frameworks category. The award trophy was handed out during the DEVIES Award ceremony on the first day of the conference.

Jakarta EE Compatible Explained

You have probably heard the term Compatible being used in the context of Jakarta EE What does it actually mean? And what is the difference between a Jakarta EE Compatible Product and a Jakarta EE Compatible Implementation? Before we dive into explaining those terms, let’s first look at the parts a specification is made up of.

The Specification Document describes the specification in textual form. Some specifications may not have a physical document but have everything described in the JavaDoc of the API component.

The API, or Application Programming Interface, is not considered a normative artifact. That means that an implementation can reproduce the API as long as the signature of the API is identical

The Technology Compatibility Kit (TCK) defines how to test that an implementation fulfills all the requirements in order to implement the specification.

At least one Open Source(*) implementation that passes the TCK is required in order for a specification to be made final.

(*) The approved Open Source licenses for ratifying compatible implementations are EPL-2.0, BSD-3-Clause, and Apache-2.0

Compatible Implementation

An implementation of a Jakarta specification is considered to be a Compatible Implementation when it can demonstrate that it fulfills all the requirements of the Technology Compatibility Kit (TCK) for that particular specification. For example, Hibernate Validator 7.0 and Hibernate Validator 8.0 are both compatible implementations of Jakarta Bean Validation 3.0. Hibernate Validator 7.0 were used as ratifying compatible implementation when Jakarta Bean Validation 3.0 was released and is therefore listed on the Jakarta Bean Validation 3.0 specification page.

Compatible Product

A Compatible Product is a Compatible Implementation of the Jakarta EE Platform, Jakarta EE Web Profile, or Jakarta EE Core Profile. In addition to fulfilling the requirements of the Jakarta EE Platform, Jakarta EE Web Profile, or Jakarta EE Core Profile TCKs, the implementor must participate in the Jakarta EE Compatibility Program to be listed on the Jakarta EE Compatible Products page.

The Jakarta EE compatible logo can only be used by those that have implemented a Jakarta EE Compatible Product as well as fulfill the requirements of the Jakarta EE Compatibility Program.

Welcome to issue number one hundred and sixty-three of Hashtag Jakarta EE!

Tuesday this week, we had the first Monthly Jakarta EE Platform Architecture call of 2023. Don’t worry if you missed it. You can check out the minutes or watch the recording on YouTube. The minutes from all Jakarta EE Platform calls are always captured on the Jakarta EE Platform Project’s website.

The conference season goes on. Last week, I was in Stockholm for Jfokus. You can read about my trip in my blog post from the trip. Next week, I will be in Oakland, California for DeveloperWeek where I will present a brand new talk about how to handle the javax.* to jakarta.* namespace switch in Spring applications.

Totally unrelated, but sort of ties into the Community Morning Runs I like to do at conferences… This weekend I ran Tjörnarparen Trail Ultra 50K and survived. Didn’t see any wild boars even if they’re known for roaming the woods in the area.

Back on topic…Remember to sign up for Devnexus. The conference will go on at the Georgia World Congress Center in Atlanta from April 4 to April 6. This year’s conference will have a dedicated Jakarta EE track. Use the code SEEMESPEAK to get a nice discount. And of course, I will arrange a morning run there as well, so make sure you bring your running shoes.

Jfokus 2023

Jfokus is one of my absolute favorite conferences. This year’s edition was no exception. The organization is excellent, you can tell that they’ve done this before. This was the 17th edition of Jfokus since it started back in 2007.

On Wednesday morning, we continued the tradition that started last year with a Jfokus Morning Run. Which made this year the second annual morning run at Jfokus.

We were 17 runners that met at 07:15 on Wednesday morning for a 5K run, and as far as I know all 17 returned and were able to attend the conference. It is truly an excellent way to start a conference day.

I had a Quickie-talk about responsible Open Source at Jfokus this year. A Quickie talk at Jfokus is a 15-minute talk, so it is pretty fast-paced. A fun experience. And I hope the participants found it interesting as well. The room was almost full, so the topic seems interesting at least.

Welcome to issue number one hundred and sixty-two of Hashtag Jakarta EE!

We have reached February, and are now a month into the first quarter of 2023. The Jakarta EE Platform Project is in the midst of putting together a release plan for Jakarta EE 11.

The goal is to propose a reliable plan for delivering Jakarta EE in Q1 2024 as formulated in the high-level guidelines for Jakarta EE 11 formulated by the Jakarta EE Working Group Steering Committee.

One of the release planning activities is gathering input from all Jakarta EE specification projects. There will be a short survey for these projects to provide input to the Jakarta EE Platform project that will be sent out early next week. One of the questions in this survey is about release plans for the individual component specifications.

With this in mind, it was extremely great to see the release plans for Jakarta Expression Language 6.0 and Jakarta Server Pages 4.0 communicated last week. Great work! Hope to see more of these shortly.

The Monthly Jakarta EE Platform Architecture call is coming up next week with an update on Project Loom in the context of Jakarta EE by Alan Bateman and Ron Pressler from the JDK Team at Oracle.

The call is scheduled for 11:00 AM ET on February 7, 2023. Check the public calendar for details on how to join.

Another thing that happened last week was that Jakarta EE 10 was awarded the 2023 DEVIES Award for best innovation in Programming Languages & Frameworks. Congratulations to everyone involved!

Welcome to issue number one hundred and sixty-one of Hashtag Jakarta EE!

We are almost a month into 2023 and the Jakarta EE Platform Project is ramping up the release planning for Jakarta EE 11. A survey will shortly go out to all the individual component specification projects to gather input about their plans. The responses from this survey will feed into the release plan for Jakarta EE 11. A draft of this release plan is in the works and will be on the agenda for the Jakarta EE Platform call this week.

The agenda for the next Monthly Jakarta EE Platform Architecture call is ready. Following the update on Project Loom in the context of Jakarta EE by Alan Bateman and Ron Pressler from the JDK Team at Oracle, we want to have a broader discussion around the implication virtual threads and other features in Java 21 will have on Jakarta EE 11.

The call is scheduled for 11:00 AM ET on February 7, 2023. Check the public calendar for details on how to join.

Jakarta EE will have dedicated track at Devnexus this year. with two full days of Jakarta EE related talks. There will even be a celebration of the 5 hyear anniversary of Jakarta EE. Maybe there will even be cake? (Vincent, this is a hint for you 😋)

If you haven’t registered for the conference yet, please use the code SEEMESPEAK to get a nice discount. This is the largest Java conference in the USA with 12 concurrent tracks, great food and networking oportunities. Not to mention the mega raffle at the end where you can win really nice prices!

Jfokus 2023 is only a week away. In addition to a quickie talk on How to Be a Responsible Open Source Citizen, I will also host the second annual Jfokus Morning Run. Sign up for the run at the Jfokus Morning Run MeetUp Event and meet me outside the Stockholm Waterfront Congress Center at 07:15 AM CET on Wednesday, February 8, 2023!

jChampionsConf 2023

This was the third edition of jChampionsConf. As the name implies, all speakers of this conference are Java Champions. The 100% virtual four-day conference (January 19, 20, 23, and 24) is available on the JChampions Conference YouTube channel.

Don’t worry if you missed a talk when it was LIVE. You can always go back and check it out at any time on YouTube!

Since I didn’t have a talk at this year’s edition, I volunteered as moderator for Has the J2EE vs Spring Infinity War reached an End Game? A short history of Java for the enterprise by Antoine Sabot-Durand. It was a very good talk where Antoine took us through the major events from the 20-year history of Enterprise Java. I highly recommend it!

Welcome to issue number one hundred and sixty of Hashtag Jakarta EE!

Last week, I was speaking at THAT Conference in Round Rock, Texas. It was my first travel in 2023, and it felt really good to be on the road again. I have a feeling that 2023 will be at least as busy as 2022. Judging by the activity on Sessionize last year, I have something to live up to.

In Hashtag Jakarta EE #159 last week, I predicted that the high-level guidelines for Jakarta EE 11 would be a major topic in the following Jakarta EE Platform calls. Unfortunately, I was not able to attend the platform call due to a conflict with my talk at THAT Conference. Judging from the minutes, it was a very productive call, and the Platform Project is eager to get started with the work of defining a plan for the release.

One of the key tasks identified is to start the work with the TCKs to be able to run with Java 21 by removing the usage of Security Manager and start early with running on Java 18, 19, and 20 to identify all potential issues with moving to newer runtimes.

I also want to remind you about the next Monthly Jakarta EE Platform Architecture call, which is scheduled for 11:00 AM ET on February 7, 2023. For this call, we are honored to have  Alan Bateman and Ron Pressler from the JDK Team at Oracle give us an update on Project Loom in the context of Jakarta EE. Check the public calendar for details on how to join.
